Patent number: 10225856Abstract: Resources are allocated on a shared downlink control channel by an allocation table that is partitioned into a first, fixed length partition and into at least one second, variable length partition. The fixed length and the modulation and coding scheme MCS of the first partition is known a priori. The second variable length and the MCS of the second partition may be given in the first partition. Robustness may be varied between different second partitions of the same allocation table, or even within a single second partition to account for users at different proximity to the network node giving the allocations. Users may be identified in the first partition (e.g., a fixed number of users), and/or in the second partition (either additional allocated users or all users being allocated if the first partition does not identify users). Method, apparatus, computer program, integrated circuit and systems are detailed.Type: GrantFiled: May 11, 2007Date of Patent: March 5, 2019Assignee: Nokia Technologies OyInventors: Jussi Kahtava, Mika Rinne, Olav Tirkkonen
